Heater and solar blanket best practices?

We’ve recently added a Hayward 96k btu heat pump to our pool and while it’s been wonderful for the kids to swim, we’re coming into our first cold snap and I’m trying to figure out what to do next.
As of this morning, the pool temp is 81 and the heater is set to 78. We put the new solar blanket on last night as well. With temps going into the low 40’s this week, should I turn the heater off altogether and just leave the solar blanket on? Or does it make more sense to leave the heater at 78 and let it maintain during the cold snap?
Thanks in advance.

Heat pump heats slowly. If you want to maintain pool heat you need to leave it on. Once you lose the pool heat it may take quite a bit of running to get back to desired temperature. Depends if you don’t mind the water not being at desired temperature when you want.
